One of the objects of the present invention is to provide a metallicroof deck or similar structure that can be quickly and convenientlyassembled and fastened in place 5 without the necessity of the workmenoperating beneath the deck. A further and important object is to providenovel fastening means that will efiectively hold the parts in place andcan be utilized in connection with 1 ordinary commercial structuralmembers. A still further object is to provide novel means for producinga joint between abutting ends of the deck members or sections.

In the accompanying drawings:

Figure 1 is a plan View of a portion of a roof deck constructed inaccordance with the present invention.

Figure 2 is a cross sectional view of the same.

Figure 5 is a plan view of the joint piece.

Figure 6 is a detail perspective view of one of the fastening clips.-

Figure 7 is a view in elevation of a yoke of said clip.

Figure 8 is an edge view of such yoke.

In the embodiment disclosed, supporting members or purlins are employedthat may be channel beams. One of these is shown at 9. The same islocated on edge to provide a horizontally disposed flan e 10, whichflange as is well known, normally tapers from the web to its free edge.This tapered formation is made use of as hereinafter explained.

Supported onthe purlins 9 and extending transversely thereof is a deckformed of sheet metal strips or members designated generally by thereference numeral 11. These members, each comprises a body or top wall12 with side walls 13 and 14 formed by flanging the margins of themetal. of the side walls, as 13,, is provided with an outstandingterminal rib or flange 15. The other side wall 14 is also provided witha terminal outstanding flange 16 preferably wider than the flange 15,and joined to the side wall by an inwardly extending bead 17.

minate short of the ends of the plate 19,

One 7 This bead produces a groove 18 at the bottom of the side wall 14and above the flange 16 (see Fig. 6). In laying the structure, themembers 11 are located side by side, as shown in Figure 2, with theflange 15 of one member fitting into the recess or groove 18 of the nextadjacent.

These members are held-in place by the following clip structures. Ateach purlin'9 a cl1p plate 19 is placed on the flange 10 thereof, sothat it lies on said flange 10 and overlies the flange 16. To positionit, said plate is preferably provided with a downturned portion 20, theends of which terforming abutment stops 21. The plate is thus reversibleand can be employed irrespective of the direction in which the flange?"10 of the purlin extends. The plate 19 is gripped to the purlin 9 by ayoke element 22 that embraces the flange 10 and plate 19, and ispreferably provided with mturned spurs 23. This yoke ma have a drivinghead 24. The distance between the free ends of the spurs 23 ispreferablysuch that the spurs will fit upon the free margin of theflange 10, but as this flange increasesin width toward the web 9, itwill be evident that the yoke must be driven into place, so that thespurs 23 will bite into the underside of the flange 10 and the upperside of the plate 19, thus effectively holding all the parts in place.

In laying the members 11, it will be noted that when one is placed .inposition, the flange 16 thereof is exposed and that consequently theworkman may stand or kneel upon this section, place the plates 19 .overthe exposed flange 16, and drive the yokes home He thus does not have towork or operate beneath the member. When he has fastened the same down,the next member is placed over the fasteners by inserting the flange 15into the groove 18. This brings the flange 16 thereof in exposedposition to be fastened and the operation is of course repeated untilthe deck is laid. It will be observed in this connection that the end ofthe plate 19 terminates short of the side wall 14, so as to permit theintroduction of the flange 15 into the groove 18. While the strips ormembers 11 may be formed of relatively great length, it becomesnecessary at times to use two or more in one rowthat is, end to end, anda novel joint is provided for this purpose, as illustrated in Figures 1,3 and 4. The ends of the adjacent members 11 are slightly separated anda channeled joint piece 25 has its ends fitted into the adjacent ends ofsaid members 11 and bridges the space between them. This joint piece ispreferabl formed of sheet metal bent to channel 0rn1,vwith its endportions preferably inset as shown at 26 to permit its ready insertion.The downturned ends 27 of the joint piece rest respectively on the bead17 and flanges l6. The central portion of the joint piece is providedwith a transverse rib 27 that fills the space between the ends of theadjacent sections 11 and is in substantial alinement therewith.

Where the end of the deck abuts a wall or other obstruction, the spacebetween one member 11. and the wall may be less than the width of themembers, in which case the structure shown in Figures 1 and 2 may beemployed. The wall herein is indicated at 28. Abutting the Wall is asection of one member, as illustrated at 29. It is provided with theside wall 14, the flange 16 and bead 17. In other'words, it may be anordinary member cut longitudinally and of course can be cut diagonallyif the wall is diagonal to the direction of the deck members 11. In thespace between the wall 14: and the first standard member 11 is a bridgepiece, comprising a top wall 30 having a. depending wall 31 providedwith a flange 32 fitting in the socket or groove of the bead 17. The topwall 30 may overlie the adjacent standard member 11 and be securedthereto by screws 33 or other fasteners. This, however, would ordinarilyprovide a single supporting wall 13 that would make a weak point in thedeck structure. In order to overcome this difficulty, a reenforcing wall34 may be employed corresponding in all respects to the wall 14 with itsflange 16 and bead 17 of a standard member. This is fitted into placeand held by clips corresponding to those already described.

As already shown this deck structure can be laid without the workmeneither lying over the top and working underneath or Working upwardlyfrom beneath because the-fasteners when placed are ex osed and readilyavailable from the tops of the deck already laid. 'Further than this, asmooth deck or floor is provided on which heat insulating material and aroof body can be placed. The structure is very strong since it issupported by a double side wall at each point and this it will be notedis true even where an obstructing wall or termination requires a specialarrangement. The

From the foregoing, it is thought that the construction, operation andmany advantages of the herein described invention will be apparent tothose skilled in the art, without further description and it will beunderstood that various changes in the size, shape, proportion and minordetails of construction may be resorted to without departing from thespirit or sacrificing any of the advantages of the invention.
